Saw Proxxon MF 70 Green 100 W 5000 OPM

The Proxxon MF 70 Green 100 W 5000 OPM is a compact, precision-focused multi-tool designed for delicate milling and drilling tasks. Built on a stable grey-cast iron base with a vertical guide and compound table, the unit provides a vibration-reduced platform for fine work. A die-cast aluminium arm housing contains a balanced 24-pin motor engineered for smooth high-speed operation. The tool supports a wide range of spindle speeds suitable for extremely small cutters and accepts multiple MICROMOT collet sizes for accurate tool holding.

Advantages

The MF 70 combines a rigid, readjustable dovetail guide system with a vibration-free motor layout to ensure precise results when working at high speeds. Its triple-slit hardened steel collets accommodate a variety of small shank diameters, and the compound table with T-slots and an adjustable ruler scale makes positioning and clamping of small workpieces straightforward. The compact dimensions and 100 W AC power input make it suitable for bench-top use in workshops where space and stability are important.

Suitable for

• Precision drilling and milling of small parts and models
• Jewellery and watchmaking component work
• Model making, miniatures, and hobbyist projects
• PCB drilling and fine mechanical adjustments

• Weight: approximately 7 kg
• Height: approximately 370 mm

How to use

Secure the MF 70 on a stable bench or stand to minimise movement during operation. Choose the appropriate MICROMOT collet for the cutter shank and securely insert it into the spindle. Set the desired spindle speed appropriate for the cutter size and material, and adjust the compound table and T-slot clamps to position and fix the workpiece using the ruler scale for accurate alignment. Feed the cutter gently into the workpiece, maintaining steady pressure and allowing the balanced motor to deliver smooth rotation. After use, turn off the unit and allow the spindle to come to a complete stop before changing tooling or adjusting setup.

Usage recommendations

Use sharp, small-diameter cutters matched to the MICROMOT collet sizes and select spindle speed according to material hardness; higher speeds suit very small cutters and soft materials while slower speeds can help with harder materials. Regularly check and, if necessary, readjust the dovetail gib to maintain play-free guidance. Ensure the work area is well lit and wear appropriate eye protection when operating the unit.
